The effect of feedback on performance and brain activation during perceptual learning

Goldhacker, Markus ; Rosengarth, Katharina ; Plank, Tina ; Greenlee, Mark W.


We investigated the role of informative feedback on the neural correlates of perceptual learning in a coherent-motion detection paradigm. Stimulus displays consisted of four patches of moving dots briefly (500 ms) presented simultaneously, one patch in each visual quadrant. The coherence level was varied in the target patch from near threshold to high, while the other three patches contained only ...
